Patented Apr. 299 193 LYMAN' O. HUFF, OF CHICAGO, ILLUN'OIS, ASSIGNOE TO'UNIVERSL OIL PRODUCTS COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OFSOUTH DAKOTA APPARATUS FOR REMOVING- CARBONACEOUS DEIOSITS FROM. OILAPPARATUS Application led July 22, i925, Serial No. 45,363. RenewedFebruary 2, 1929.

This invention relates to improvements in apparatus for removing carbonmaterial that has deposited in the enlarged reaction chamber'of a tubeand drum oil cracking appa- One of the objects of the invention is toprovide means for breaking up the mass of deposited carbon so that itmay be easily' removed from the chamber. It is also an object of theinvention to so construct the apparatus that it may be easily positionedin the reaction chamber and readily withdrawn therefrom. i

In they drawings,-

Figure 1 is a sectional view in side elevation of an enlarged verticalreaction chamber showing my invention applied thereto.

Fig. 2. is a horizontal sectional view of j the structure shown in Fig.1.

The reference character 1 designates an enlarged vertical reactionchamber of a type in general cormnercial use with tube and drum crackingprocesses. This reaction chamber l is provided with a heated oil inletline 2 controlled by suitable valve 3 as well as with a vapor outletline 4 controlled by valve 5 throu h which vapors evolved from theheated oil introduced to the chamber pass to a dephlegmator or condenser(not shown) The reaction chamber may be provided with the usual manholecovers at the top and bottom as indicated at 6 and 7. r

Coming more particularly to the novel feature of my invention, Iprovideannular rows 5 of hooks or suitable fastening devices around thetop of the reaction chamber on the interior thereof as indicated at 8and 9, the inner row 8 being preferably positioned relatively e close tothe upper opening of the chamber while the outer row 9 may be dis osedat a substantial distance therefrom. sus end from these annular rows ofhooks a single continuous dexible element such as a metallic chain orcable. In the drawings I have shown a chain 10. It will, of course, beunderstood that a cable may be employed. The end 11 of this'chain isreleasably supported by) one of the hooks or fastening devices in t erow 8. The chain passes down to a point near the bottom of the chamberand is thence doubled back to a second hook in the row 8, passed to athird hook in such row and again looped to a point adjacent the bottomof the chamber, this o eration being continued until the chain has eenreleasably fastened5 as for example, by light gauge Wirev as shown atl2, to all of the hooks in the row 8. The chain is thence led to the row9 and similarly secured to all of the hooks or tasten-y ing devices ofthat row. The free end of the chain shown at 13 is shown as positionedat the bottom of the chamber so that it will be readily accessible whenthe cover Z is opened. l

It Will be readily apparent that the-chain 10can be withdrawn eitherfrom the top of the chamber or from the bottom of the chamber.Ifdesired,` the end 1l of the chain can .be suitably connected to aWinch and the chain withdrawn through the top of the chamber. If it ismore convenient the chain can be Withdrawn from the bottom of thechamber by securing the end 13 to a suitable Winch mechanism.

One of the great diiiiculties incident to employing vertical reactionchambers is that the carbon deposits to a considerable depth in thechamber and is exceedingly diicult to remove. The alternate looping atthe bottom and top of the chamber of the chain 10 in my improvedapparatus causes this mass of deposited carbon to be very completelybroken up when the chain is Withdrawn. The positioning of all of thefastening elements by which the chain is secured at the top of achamberpermits of ready application of the chain to .an empty chamberpreparatory to commencing a run.

What I claim as my invention is:

.An ap aratus for disrupting and removing car on from an enlargedreaction chamber in an oil cracking apparatus, comprising a singlecontinuous iexible element releasably suspended intermediate its endsfrom a plurality of spaced points at the top of the chamber differentintermediate portions of said iiexible element being vertically disposedthroughout the entire depth of deposited carbon in the reaction chamber,said exible element adapted to be withdrawn from the chamber to disruptthe carbon deposited therein. y p

3. An apparatus for disrupting 'and removing carbon from an enlargedreaction chamy ber in an oil cracking apparatus, comprising a singlecontinuous exible element releasably suspended intermediate its 'endsfrom a plurality of spaced points at the top of'the chamber, diii'erentportions of said iexible element being disposed vertically through thevmass of deposited carbon in the reaction chamber, said flexible elementada ted to be Withdrawn from the chamber to srupt the carbon depositedtherein.
